AS APPLIED TO MAN. , 313 
it have been of the men whose sole weapons were 
rudely chipped flints, and some of whom, we may 
fairly conclude, were lower than any existing race ; 
while the only evidence yet in our possession shows 
them to have had brains fully as capacious as those 
of the average of the lower savage races. 
We see, then, that whether we compare the savage 
with the higher developments of man, or with the 
brutes around him, we are alike driven to the con- 
clusion that in his large and well-developed brain 
he possesses an organ quite disproportionate to his 
actual requirements—an organ that seems prepared in 
advance, only to be fully utilized as he progresses in 
civilization, A brain slightly larger than that of the 
gorilla would, according to the evidence before us, 
fully have sufficed for the limited mental development 
of the savage; and we must therefore admit, that the 
large brain he actually possesses could never have 
been solely developed by any of those laws of evolu- 
tion, whose essence is, that they lead to a degree of 
organization exactly proportionate to the wants of 
each species, never beyond those wants—that no pre- 
paration can be made for the future development of 
the race—that one part of the body can never increase 
in size or complexity,,except in strict co-ordination to 
the pressing wants of the whole. The brain of pre- 
historic and of savage man seems to me to prove 
the existence of some power, distinct from that which 
has guided the development of the lower animals: 
through their ever-varying forms of being.
